如何让局域网中.local后缀隐式生效？解决主机名解析失败问题

Absolutely, there are a couple of straightforward ways to make that .local suffix work implicitly—so you can just type pleurotus instead of pleurotus.local every time. Let’s break down the most reliable methods based on your operating system:

This is the simplest solution if your pleurotus host has a static IP address. Here’s how to set it up:

• First, get the IP of pleurotus.local: Run ping pleurotus.local in your terminal/command prompt—you’ll see the device’s IP address in the output (e.g., 192.168.1.105).
• Edit the hosts file:
  • Windows: Open Notepad as Administrator, then navigate to C:\Windows\System32\drivers\etc\hosts. Add this line at the bottom (replace the IP with the one you found):

    192.168.1.105   pleurotus
    

    Save the file to apply changes.
  • Linux/macOS: Open a terminal and run sudo nano /etc/hosts (use vim instead of nano if you prefer that editor). Add the same IP-hostname line at the bottom, then save and exit (for nano: press Ctrl+O, hit Enter, then Ctrl+X).
• Flush your DNS cache to make the change take effect right away:
  • Windows: ipconfig /flushdns
  • macOS: sudo dscacheutil -flushcache; sudo killall -HUP mDNSResponder
  • Linux (systemd-based): sudo systemctl restart systemd-resolved

If pleurotus uses a dynamic IP (assigned via DHCP), the hosts file method will break if the IP changes. Instead, set your system to automatically search for hosts in the .local domain:

• Windows:
  1. Open Control Panel → Network and Sharing Center → Click your active network connection.
  2. Click "Properties" → Double-click "Internet Protocol Version 4 (TCP/IPv4)".
  3. Click "Advanced" → Go to the "DNS" tab.
  4. Under "DNS suffix search list", click "Add" and enter local, then click "OK" to save all changes.
• macOS:
  1. Open System Preferences → Network → Select your active network.
  2. Click "Advanced" → Go to the "DNS" tab.
  3. Click the "+" button under "Search Domains" and enter local, then click "OK" and "Apply".
• Linux (NetworkManager):
  1. Open your system’s network settings (e.g., GNOME Settings → Network).
  2. Click the gear icon next to your active connection → Go to the "IPv4" tab.
  3. Under "DNS", add local to the "Search Domains" field, then save the settings.

Once you set up the DNS search domain, your system will automatically try appending .local when you ping pleurotus, so it’ll resolve exactly like pleurotus.local does.
